mac80211: handle deauthentication/disassociation from TDLS peer commit 79c92ca42b5a3e0ea172ea2ce8df8e125af237da upstream. When receiving a deauthentication/disassociation frame from a TDLS peer, a station should not disconnect the current AP, but only disable the current TDLS link if it's enabled. Without this change, a TDLS issue can be reproduced by following the steps as below: 1. STA-1 and STA-2 are connected to AP, bidirection traffic is running between STA-1 and STA-2. 2. Set up TDLS link between STA-1 and STA-2, stay for a while, then teardown TDLS link. 3. Repeat step #2 and monitor the connection between STA and AP. During the test, one STA may send a deauthentication/disassociation frame to another, after TDLS teardown, with reason code 6/7, which means: Class 2/3 frame received from nonassociated STA. On receive this frame, the receiver STA will disconnect the current AP and then reconnect. It's not a expected behavior, purpose of this frame should be disabling the TDLS link, not the link with AP.
